Let us see why that is the case. Issue with D-IRP mechanism for Composite Devices Now let us see what happens if the function drivers managing individual functions of the composite device, in the preceding example, tried to use There are two different mechanisms for selectively suspending a USB device: idle request IRPs (IOCTL_INTERNAL_USB_SUBMIT_IDLE_NOTIFICATION) and set power IRPs (IRP_MN_SET_POWER). http://mwdsoftware.com/selective-suspend/usb-selective-suspend-on-or-off.php USB 3.0 defines link power management (LPM) with different link states from U1 to U3 in the increasing order of power savings and in the increasing order of exit latencies.
Therefore it is imperative for USB devices and their function drivers to implement this feature.

When the user initiates the transfer process (by using a certain application), the power policy owner gets an I/O request from the application, and knows that it needs to wake up The following figure illustrates this process. Instead, when the driver sends a particular link to U3 by sending a control transfer to the hub, the downstream device connected to that link goes directly into a suspend state.
This mechanism is known as selective suspend. A device that is in selective suspend should be able to send resume signal when any user action that it would normally respond to. Apparently the selective suspend feature was putting my mouse and keyboard's USB ports into the suspend state, and I have yet to figure out why that prevented me from waking the Comments (6) Cancel reply Name * Email * Website Hannes says: May 25, 2011 at 11:44 pm Excellent atricle, thanks for demystifying 😉 But please re-post the diagram images without the
